OBJECTIVE The aim of this study was to evaluate the cause and treatment of atrial flutter after coronary artery bypass grafting (CABG). METHODS Between July 1999 and July 2000, 96 CABGs were performed at the Cardiovascular Center of Aichi Prefectural Owari Hospital. We compared two groups of patients: those with atrial flutter after CABG (group A) and those without atrial flutter (group B). ...

INTRODUCTION Atrial fibrillation and atrial flutter account for one third of hospitalizations due to arrhythmias, determining great social and economic impacts. In Brazil, data on hospital care of these patients is scarce. OBJECTIVE To investigate the arrhythmia subtype of atrial fibrillation and flutter patients in the emergency setting and compare the clinical profile, thromboembolic risk a...

OBJECTIVE Atrial flutter is an uncommon arrhythmia in the pediatric population except for the immediate newborn period or following atrial repair of congenital heart disease. In children the diagnosis of atrial flutter may be difficult, attributable to rapid atrioventricular conduction and superimposition of flutter waves on QRS and T waves. Atrial flutter secondary to hyperthyroidism has been ...

To avoid atrioventricular node-His bundle ablation, catheter ablation of the atrial myocardium was attempted in eight patients with drug refractory type I atrial flutter. In seven of eight patients, a zone of prolongation and fragmentation of the endocardial electrogram was found in the low posterior part of the right atrium. Entrainment of the atrial flutter by high right atrial pacing was acc...

If human atrial flutter is due to re-entrant excitation, depolarization as well as repolarization must continue throughout the entire atrial cycle. It follows that the atrial vulnerable period for inducing atrial fibrillation is also continuous rather than discrete. This hypothesis was examined during cardioversion of I33 patients with atrial flutter who received 280 low-energy shocks. A compos...

I read with interest the article by David et al. regarding a case of recurrent tachycardia-induced cardiomyopathy secondary to typical atrial flutter. I have some concerns regarding the management of the recurrences of atrial flutter and tachycardiainduced cardiomyopathy in this case. The authors’ choice of treatment involved DC cardioversion of the atrial flutter that was successful in restori...

BACKGROUND Although most ablative procedures undertaken for common atrial flutter target the inferior right atrial isthmus, comparative studies of the morphology of this area are lacking. Our study examines its angiographic anatomy, making correlations with postmortem specimens, to provide a better understanding of the anatomic substrate of this arrhythmia. METHODS AND RESULTS The gross morph...

OBJECTIVE To assess the changes in quality of life, arrhythmia symptoms, and hospital resource utilisation following catheter ablation of typical atrial flutter. DESIGN Patient questionnaire to compare the time interval following ablation with a similar time interval before ablation. SETTING Tertiary referral centre. PATIENTS 63 consecutive patients were studied. Four patients subsequentl...

OBJECTIVES This study sought to study the change in autonomic tone that precedes the initiation of paroxysmal atrial flutter. BACKGROUND An abrupt change in the autonomic tone of the heart is an important initiating factor in the pathogenesis of ventricular tachyarrhythmias and paroxysmal atrial fibrillation. Whether the autonomic tone has a role in the initiation of paroxysmal atrial flutter...
